I have a 93 Civic DX Coupe with a 98 B20B motor and a 98 ITR transmission. The car runs great but the rev limit is 6000rpms and has a top speed of 110mph. I was wondering what I could do to raise them.

 

what ecu rev limits at 6k?

 

get a new ecu from like a itr

 

Get an OBDI P75, it will raise it up to the 7300rpm, but that's about all you can do.

ITR = P73 = OBDII

 

Thats what I am going to do then. Is there anything major I will have to do to put the P75 in or do I just unplug the old one out and plug the new one in?

I also have a 98 ITR head, Im not exactly sure what that would do if I put it on though. What would putting that head on do for the car?

 

You said B20B, so I automatically assumed it was a B20B, NOT a CRVTEC. P75 won't work in your situation.

Either get a chipped P28, a P30, or last resort P72.

 

I havent put the ITR head on the car yet, I am still undecided whether or not to do it, it seems like a big job.
